having a universal assert function (similar to nodejs' assert builtin)
might be useful. it could be name "assertOrThrow" for web-compat.
this would simplify writing common-case "throwaway" error-handling behavior
in both browsers and nodejs:
```js
// naive polyfill
globalThis.assertOrThrow = globalThis.assertOrThrow || function (passed,
message) {
/*
* this function will throw error <message> if <passed> is falsy
*/
if (passed) {
return;
}
throw (
typeof message === "object" && message
? message
: new Error(message)
}
};
localforage.setItem("foo", "bar", function (err, data) {
// validate no err occurred
// this one-line statement makes writing test-coverage less tedious
assertOrThrow(!err, err);
...
});
```
